Abstract: PURPOSE: To provide a coral ceramic functional physiologically active negative ion air generating method using ultrasonic vibration. CONSTITUTION: In this method, a coral calcining means B calcines weathered coral into coral powder. In a container 2 for desorbed water, in which a coral ceramic cartridge 1 and water are contained, coral ceramic produced in the coral calcining means B is reacted with water W from a water inlet, so that the water W is alkali-ionized. An ultrasonic oscillator 6 gives oscillation to alkali ion water produced by reacting the coral ceramic with the water W in the container 2 for desorbed water. Finally, a fan 7 gives wind power to negative ion air discharged from the ultrasonic oscillator 6. Thereby, the apparatus has a very low cost and its effect can be improved by using ultrasonic wave or wind power.
